Sam’s Tours & Unique Dive Expeditions are experts in diving during full & new moon cycles when different fish species gather in huge numbers to spawn. Wild excitement. This small group trip within the Dive Advice Network is led by two colleagues from Behind the Mask. Only 6 guests per trip. 


So, during the full moon, it’s the snappers who put on the show … but when it’s time for the new moon, it’s the bumphead parrotfish. And, oh, what a show it is ! Often seen patrolling the reefs in schools of up to 20 or more, these encounters are favorites for many divers, but imagine being in the water with nearly a thousand of these uniquely weird but beautiful creatures!

The New Moon Expedition takes you to a remote dive site, where the bumpheads begin forming groups early in the morning. Awaiting the exact time for spawning, hundreds of bumphead parrot fish from all around the area come together for an unforgettable event.

In the build-up, you’ll observe the behavior of the males, as they begin their display of dominance, attempting to attract as many mating partners as possible.  As the females continue to gather, the school spills out into the blue where the tension erupts into a climatic mating dance.


Sam’s Tours has partnered with Unique Dive Expeditions the past couple of years to offer some of the full moon and new moon trips.

Due to the nature of the strong currents affected by the moon phase, which also brings aggregations of fish together to spawn at dawn, Unique Dive Expeditions is not for everyone.

Unique Dive Expeditions is only open to experienced divers (over 50 dives) who are thoroughly comfortable in the water.  Divers must be able to swim against strong currents and deploy their own surface marker buoy in case they separate from the group.

Please note that trips such as spawning event are a very special experience which can never be guaranteed. There is no guarantee of an animal encounter or the perfect underwater photo. It is nature, just like everywhere else. The beauty lies in its unpredictability.

We highly recommend DiveAssure insurance which also covers force majeure and single missed days of diving due to sickness. Feel free to ask us about it.. 

Further extensions are always possible and we’re happy to assist!
